application filed Maren 23, 191.6, Serial No. $5,121. Renewed January 2, 1919. Serial No. 269,390.

To all whom 'it may concern Be it known that l, Bom-:nr S. Bomen, a citizen of the -United States, residing at Richmond Hill, in the county of Queens and State of New York, have invented new and useful improvements in Paper Barrels of which the following is a specification.

rhis invention relates to barrels, the main .object of the invention bein to produce a reinforced barrel the body oi' which is composed of a continuous web of flexible nia terial such as paper or thev like in any of the forms thereof capable of being expanded or stretched for the purpose of producing abarrel body of the bilged type or, in other Words, a barrel body in which the ends are of less diameter than the center, the same as the ordinary wooden barrel of staved formation now in common use.

lVith the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed.

ln the accompanying drawings Figure l is a plan vie`w of a partially corrugated web of material from which the body of the barrel is made.

Fig. l() is a section on the line 10j-l0 of Fig. 1.

lin producing a barrel in accordance with the present invention, a Web of paper indicated at 61 is irst dampened in order that it may be stretched. llt is then passed through a suitable machineI and the web is stretched longitudinally between the side margins thereof, the central or medial portion of the web being stretched to the greatest eX- tent and the stretching of the web then diminishing toward the-side orllongitudinal margins thereof. The web after being dampened and stretched in the' mannaer referred to is wrapped around a forni or Inandrel, an adhesive being applied to the Web as -it is Wrapped around the mandrel and upon itself to form superimposed plies or layers and rolling pressure being applied to the initial and subsequent convolutions or wrappings of the web as they are wrapped around the mand rel.

ln the description of the article, the body ofthe barrel is made up of a web 6l of paper wound around a mandrel to produce a plurality of superimposed plies or layers 65 of material (see Fig; 5) wrapped in contact with an adhesiif'ely united or attached to each other. Between the layers of material may be placed strips or bands 66 of a like or unlike material. The interposed strips or bands not only act as strengthening means,

but in addition create an annular enlarge-v ment or bulge of the walls in an outward direction at these points. At the intermediate poi nts Where the additional material is placed, a. hoop or band 66 may be crimped over both edges of the annular protuberance. fit the extremities or the head endsiof the barrel, they create a` shoulder or gripping edge for the turned in or curled edge 67 of the outer chine hoop G8 of the head holding means. This outer hoop acts as a. retaining medium' for an inner hoop 69, having an annular inclined wall 70 vbelow which may be inserted a wire hoop 71 in the retaining channel v72. Below the Wire hoop retaining channel is a.

head reeeivinoseat 73 hai/ino' an annular 2") 7 'j head supportinga lip 7d from which thel Walls of the hoop return toward and rest against the inner surface of the body of the barrel.

At the center of the barrel or bilge section is placed an internal hoop, the construction of which is best shown in 5.' Before being entered into the barrel, this hoop is of a W cross section, with the long legs 75 at the center and two shorter legs 76 toward the extremities. After the hoop is inserted in the barrehpressure is applied to the legs 75 causing` them to assume a U shape7 as shown in ful] lines. This distortion increases the lto outer diameter of the hoop so as to cause the saine to crowd against the inner Walls of the barrel, and in this manner prevents its dislodgment duringl usage.

in Fig. (i is shown in dot and dash lines the -Wire hoop 7l in a distorted formation. .lo insert this Wire hoop, one edge is crowded under the projecting lip 77 of the head retaining hoop, and as the pressure is applied circiunfcrentially, the hoop 71 assuming' its natura-l or circular formation is by this pressure or crowding action forced inte Ythe chai'inel 72, thereby crowding the upgjier lever or disk 78 of the head downward, alsoA :forcing the lower or cup shaped d.- l( 79 of the head over the cor Ler 80 of the head receiving hoop.

lt will be noticed by referring to 'Figa 9, that 'the lower disk 79 ott' the head is slightly flared and larger in dianieter. than the re" ceiving seat 73 of the hoop, also that normallythe top dislr 78 oi the head is a flat' dislr material. i

lt 1s then obvious that the crowdlng of f the wire hoop 7l into the channel 72 Will cause the heed to crowd against Athe corner l" einst the Wall. 73, and against the Wire "Il, thereby forming a. perfect closure of the barrel by the head.

in the inner hoop or head receiving means of the barrel, on the inclined face 70, will bc noted a depression 81, into which,

for the removal of the head holding wire hoop,l may be inserted any pointed instrunient such as a screw driver or other tool, an inward pressure of which will force or pry the Wire hoop trom its seat, after which it may be readily sprung into a distorted shape and removed, leaving the head free' to be taken out. y

lif'hc external oisets formed by the circInnfcreDtial strips incorpora-ted between the plies of the barrel body serre to resist and withstand internal outward pressure While a biige sustaining band within the center the barrel body serves to Withstand external inward pressure. All of said bands thus mutually contribute to reinforce and strengthen the barrel and render the same practical for heavy duty service. The

chine forming band also assists the other' bands in the same Way and for the same purpose, thus producing a. very strong and practical paper barrel of the closed or impert'ora-te type,

Having thus described my invention, Il claim il. fr bilged barrel body composed of a continuous web of paper Wrapped upon itself to form a barrel body embodying a -continuous web of paper Wrapped upr circumferentiully of the end of the sustaining expansion ring located Within the barrel body and midway between the ends thereof, said ring being expiinsible after its insertion in the barrel body'.

2. A bilged barrel body composed'of a continuous web of sheet material of sufficient length to form a barrel body embodyn ing a plurality of superimposed layers, a strip interposed between 'the layers and producing an annular reinforcing offset, and a self-retainingl binder encircling said odset.

3.'A bilged barrelbdy composed o1 a continuous web of sheet material of Suthcient lenghthto form a barrel body embody ing aplurality of superimposed layers, a strip interposed between the layers and producing' an annular reinforcing offset, and an annuler binder encirling said offset and having a barrel head supporting portion extending into the end of the body.

4. A bilged barrel body composed i. .sl a

self to torni ai barrel body embody plurality of superimposed plies, a stri;y tending circuinferentially of the body interposed between the plies 'thereof exand and producing an annular reinforcing hoop-like offset, and a binder encirclingr said offset,

5.211 bilged barrel body composed of a continuous web of paper Wrapped upon itself to form a barrel body embodying a plurality of superimposed plies, a strip eX- 'tending oircuniferentiu-lly of the body interposed between the plies thereof and pro' ducing an annular reinforcing hIoopd-ike offset, and a lodge-sustaining expansion ring located Within the barrel body and midway between 'the ends thereof.

6. A bilged barrel body composed of a continuous web of paper wrapped upon itself into'barrei formation, a. strip extending body and interposed between. the Wrapped plies thereof producing an external hoop-lilie offset, and a. chine band embracing the adjecent edge of the body and having an outer portion which embraces, engages and is retained by said oil'set and also having an inner portion which lies `Within the barrel body and is formed with a barrel head receiving seat and also an annular groove to receive a barrel head retaining hoop,
